“This is very strange, Mr. Bayne,” she was saying idly. “I understood that you were to drive an ambulance at the Front.”

How young, how lovely, how glowing she looked as she stood there in her snowy dress. I found myself wondering impersonally what had led her to these devious paths.

“Mr. Bayne,” she demanded, “are you a secret-service agent?”

“Good heavens!” I exclaimed, startled. “No!”
